Ok I have a 2001 Jeep Cherokee Sport with inline 6 4x4 with about 67000 miles on it. The a/c will work fine sometimes and other times it will not turn on at all. Tonight I started it and let it run for 10 minutes with the air on. It rain the full 10 minutes and never cycled off, I dont know much about a/c but shouldnt the clutch have stopped or something should have clicked to turn the air off for a little while. It got so cold the windows were fogging, so I know it gets cold enough. So im thinking the coil is freezing up and not working after that. Its charged correctly according to guages, so I dont think thats it. Any help would be appreciated. Thanks
